A Cognitive Study of English Polysemy and Its Implication for Vocabulary Teaching ---Based on Conceptual Metaphor Theory

多义词，即一词多义，在英语及任何其他语言中占据主导地位而单义词则为少数。我们日常生活中使用的用于表示熟悉事务的常用词大部分是多义词。作为一种常见的重要的语言现象，多义词已经引起了哲学家、心理学家和语言学家们的重视。尤其是语言学家们，他们对多义词的成因和发展路径产生了浓厚的兴趣。传统语言学家，如Aristotle和Breal，认为语言是任意的、抽象的和不能体验的，多义词的多义项的发生是巧合的。结构主义语言学家们在研究多义词多项意义之间的联系时，过于关注于语言形式的内部结构，却忽略了影响多义形成的外部因素—使用语言的人，包括人类的认知手段、生活体验等。结果他们的研究没有把握多义词的实质，无法对一词...Polysemy means literally a plurality of meaning, and it refers to a word which has two or more different meanings. In English as in any other language polysemy is the rule and monosemy is the exception. Most of the common words denoting familiar objects in our daily life have various meanings. Being a general and important phenomenon in language, polysemy has won attentions from philosophers, psyc...学位：文学硕士院系专业：外文学院外语教学部_英语语言文学学号：X200711101

Establishment of a method to quantitatively detect FLT3 internal tandem duplication in acute myeloid leukemia with denaturing high-performance liquid chromatography

目的:建立一种应用变性高效液相色谱技术(dHPlC)相对定量检测急性髓细胞白血病(AMl)患者fMS样酪氨酸激酶3(flT3)基因的内部串联重复(ITd)突变的方法。方法:根据flT3-ITd突变基因多位于14外显子而设计引物,用聚合酶链反应(PCr)方法特异性扩增121例AMl患者flT3-ITd突变基因,再用dH-PlC技术相对定量检测flT3-ITd等位基因突变的情况;与毛细管电泳法(CE)检测突变的结果对比进行该方法的有效性检验;最后与121例样品PCr扩增产物的测序结果进行对比。结果:经dHPlC分析后均能得到特征性的洗脱峰。121例样本中检测到flT3-ITd突变阳性的样本13例,总阳性率为10.7%,阳性突变等位基因的比例不一,分布范围中位数为34.5%(11.4%-80.2%),为21-87 bP单个插入片段。阳性率和突变比例与CE方法检测结果相比较均无显著差异(P>0.05),并与121例样本flT3-ITd扩增PCr产物基因测序结果一致。结论:成功建立了一种应用dHPlC相对定量检测AMl患者flT3-ITd基因突变的方法。AIM: To establish a relatively-quantitative method to detect the internal tandem duplication(ITD) mutation of Fms-like tyrosine kinase 3(FLT3)gene in acute myeloid leukemia(AML) patients using denaturing high-performance liquid chromatography(DHPLC).METHODS: According to the fact that much more FLT3-ITD mutations are located in exon 14,we designed the primers,and use the method of polymerase chain reaction(PCR) to specifically amplify FLT3-ITD mutation gene in 121 cases of AML,and relatively quantified the situation of mutant allelic gene of FLT3-ITD by the method of DHPLC.The effectiveness of DHPLC was verified by the method of capillary electrophoresis(CE).The sequenced results from PCR amplified products of 121 samples were compared.RESULTS: A characteristic of elution peak was detected by DHPLC with 10.7% overall positive rate(13/121) and varied in the proportion of mutant alleles,with a single duplicated insert fragment from 21 bp to 87 bp.The median range of mutant alleles was 34.5%(11.4%-80.2%).No significant difference of the positive rates and mutation proportions between the results with DHPLC and the results with CE method was observed.The results of FLT3-ITD mutant gene of 121 samples were consistent with the results using sequencing method.CONCLUSION: A relatively-quantitative method to analyze AML patients with FLT3-ITD mutation by DHPLC is successfully established

南海中深层动力格局与演变机制研究进展

南海是连接印度洋-太平洋的最大边缘海,在季风、海峡水交换以及复杂地形影响下,南海环流呈现出独特的三层结构以及远强于大洋的混合特征.理论与观测表明,南海内潮、内孤立波以及强风等过程是强混合的动力来源.在南海强混合作用下,南海发育了活跃的中深层动力系统,一方面促进了南海与大洋之间的水体交换,另一方面调控上层风生环流,使得南海环流显著区别于其他热带与副热带海盆.南海活跃的中深层环流所具有的物质搬运能力又显著影响着南海的地质沉积、生物地球化学循环等过程.中国对深海研究持续投入,在南海中深层环流动力学研究方面取得了显著的成果,文章就该方面进行总结,并对南海深海环流未来研究设想进行初步探讨

Two I-h-symmetry-breaking C-60 isomers stabilized by chlorination

Setting it apart from the other 1,811 topological isomers (isobuckminsterfullerenes) is its exclusive conformity with the isolated-pentagon rule(3), which states that stable fullerenes have isolated pentagons. Although gas-phase existence of isobuckminsterfullerenes has long been suspected(4-7), synthetic efforts have yet to yield successful results. Here, we report the realization of two isobuckminsterfullerenes by means of chlorination of the respective C-2v-and C-s-symmetric C-60 cages. These chlorinated species, (C60Cl8)-C-#1,809(1) and (C60Cl12)-C-#1,804(2), were isolated in experimentally useful yields. Structural characterization by crystallography unambiguously established the unique pentagon-pentagon ring fusions. These distinct structural features are directly responsible for the regioselectivity observed in subsequent substitution of chlorines, and also render these unprecedented derivatives of C60 isomers important for resolving the long-standing puzzle of fullerene formation by the Stone-Wales transformation scheme(8-11).NNSF of China,20525103 ,20531050 ,20721001 , 20571062 ,20425312 973 Program 2007CB81530

1978年以来长江三角洲地区经济格局动态变化研究

长江三角洲地区自1978年以来经济的快速发展推动着区域经济格局的演变。采用1978-2005年长江三角洲16市GDP数据,首先计算分析区域GDP增加的总量与速度,定量描述区域经济的不平衡性,进而引入区域重心的概念,定量表示出长江三角洲地区改革开放以来GDP重心的动态演化过程。结果表明:长江三角洲地区GDP增长速度较高的城市主要沿宁沪杭甬铁路呈"Z"型分布;发展速度较低的主要分布在长江三角洲边缘及两翼地区;上海市与第二位城市的差距有所减小;区域GDP重心整体上表现出缓慢、定向的向西南移动趋势,表明区域差异总体上在不断缩小
